Update `JdkUnsafe` intrinsics.

The `jdk.internal.misc.Unsafe.getObject*()` methods have
been replaced with `getReference*()` and the old methods
just forward to the new ones for backward compatibility.
Update ART to pick up the new methods as intrinsics to
support code that references them directly.

Similarly update intrinics for other deprecated
`JdkUnsafe.*Object` methods.
